In the fields of psychology and psychiatry, the use of the terms impulsivity, sensation-seeking and ordalie to refer to risk-taking behaviors can sometimes be confusing.
The objective of this study was to establish a clinical definition of the concepts of ordalie, sensation-seeking and impulsivity, in order to analyze the similarities and differences between these concepts.
We prioritized literature review articles with or without meta-analysis from the Medline database and supplemented with the Google-Scholar database. The articles were included in this review if their objectives were in line with ours. The research was conducted in November 2018.
Twenty-seven articles were selected. There are similarities in the clinical definitions of these concepts with measurable heterogeneous constructions, and an exacerbation in adolescence for engagement in harmful behaviors, but there are also nuances that highlight their differences.
We were able to describe areas of divergence and convergence between these three concepts but not to establish a quantitative diagram of the areas of divergence and convergence. It would seem that the coexistence of sensation-seeking and impulsivity in the same individual could explain that individual's involvement in ordalique behaviors. Further studies approaching this hypothesis would seem useful in terms of preventing risk-taking behaviors such as addictive behaviors.

We carried out a biofeedback psychotherapy protocol with rTMS (twenty sessions, two sessions per day for ten days; 1Hz, 150% of the motor threshold, twenty minute sessions, 300 pulses per session) in which the patient visualized the motor activity of her upper limbs during stimulation of the primary motor area (PMA). The evolution of neurological symptoms was assessed using the Medical Research Council Scale for Muscle Strength (MRC).
Symptoms were improved between the 4th and 6th days of treatment (8th and 12th sessions) with first a relief of paresis, then a secondary cascade improvement of other functional symptoms. At two months the patient no longer presented any functional neurological symptoms.
We propose several hypotheses concerning the effectiveness of this type of biofeedback protocol using rTMS. We also suggest that this type of protocol should be systematically associated with psychotherapeutic support on biographical elements for holistic management. This observation underlines the interest of potentiating cognitive-behavioral therapies using the principle of operant conditioning with the aid of brain stimulation in functional neurological disorders, and motivates the realization of future studies.

This is a retrospective observational cohort study of 2010-2015 data from the Nationwide Emergency Department Sample (NEDS). The NEDS is a sampling of ED visits across 953 hospitals in 36 states. Unintentional falls for children with and without developmental disabilities were compared, adjusting for age, sex, payment source, income, mechanism, injury severity score (ISS). A sensitivity analysis was then performed for children with ADHD (n=139,642) and those without any developmental disabilities. A priori chosen outcomes included hospital admission, length of stay, intubation, and surgery. Logistic regression analysis estimated adjusted odds ratios for outcomes.
Among children who presented to the ED with unintentional falls (n=13,217,237), there were 223,445 (1.7%) with developmental disabilities. The maidance and attention to adequate treatment to prevent injuries from unintentional falls.
Children with developmental disabilities, in particular those with ADHD, who experience falls are often older and male. They had greater odds of poor outcomes. These children need additional anticipatory guidance and attention to adequate treatment to prevent injuries from unintentional falls.Brain activity complexity is a promising correlate of states of consciousness. Previous studies have shown higher complexity for awake compared with deep anaesthesia states. However, little attention has been paid to complexity in intermediate states of sedation.
We analysed the Lempel-Ziv complexity of EEG signals from subjects undergoing moderate propofol sedation, from an open access database, and related it to behavioural performance as a continuous marker of the level of sedation and to plasma propofol concentrations. We explored its relation to spectral properties, to propofol susceptibility, and its topographical distribution.
Subjects who retained behavioural performance despite propofol sedation showed increased brain activity complexity compared with baseline (M=13.9%, 95% confidence interval=7.5-20.3). https://www.selleckchem.com/products/l-alpha-phosphatidylcholine.html This was not the case for subjects who lost behavioural performance. The increase was most prominent in frontal electrodes, and correlated with behavioural performance and propofol susceptibility.
